High-pass filter used; intervals shortened. Recorded along the Pepper Road Trail in deep forest. Bird was singing distantly, which I initially recorded, then played back THAT recording which called the bird in closer.

The antbird was calling from low brush, and flushed as I approached to record better. I did not see the bird well (other than that it looked like an antbird), but my guide, Nando Quiroz, knew its call. The bird flew about 100 m away, then I heard (but did not record) its regular song (like XC271432) from where it went.
